Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
ERBB4, a member of the epidermal growth factor receptor (EGFR) family, plays a pivotal role in various cellular processes including proliferation, differentiation, and survival. Its unique receptor isoforms, generated through alternative splicing, contribute to diverse signaling pathways that are crucial in both normal physiological functions and pathological conditions, such as cancer. Recent studies have highlighted ERBB4's importance not only in tumor biology but also in neurodevelopmental processes, particularly in the brain where it influences neuronal communication and synaptic plasticity. The dysregulation of ERBB4 signaling has been implicated in several disorders, including schizophrenia and various forms of cancer, making it a potential therapeutic target. As such, the development of ERBB4 recombinant proteins is gaining attention, as these proteins can be utilized to elucidate the receptor's function, identify interaction partners, and screen for small molecule inhibitors. By harnessing recombinant DNA technology, researchers can produce these proteins in sufficient quantities for detailed biochemical and biophysical analysis. Understanding the structure-function relationship of ERBB4 through its recombinant forms is crucial for the design of novel therapeutic strategies aimed at modulating its activity in disease contexts. As research progresses, ERBB4 remains a significant focus in the field of molecular biology and cancer therapeutics, paving the way for innovative interventions to combat associated diseases.
